Computed versus measured response of HDR reactor building in large scale shaking tests

Experimental investigations of nonlinear effects were performed with an extremely heavy shaker at the HDR reactor building. The objective was the dynamic response behaviour of the structure, piping and components to strong earthquake-like shaking including nonlinear effects. This paper presents some results of safety analyses and measurements, which were performed prior and during the test series. It was intended to shake the building up to a level where only a marginal safety against global structural failure was left. (orig./HP)
